Two-month-old citrus rootstock seedlings of Cleopatra mandarin (CM) and Carrizo citrange (CC) were fertilized with nutrient solution, with or without additional 50 mM NaCl, and grown under either ambient CO 2  (aCO 2 , 360 ppm) or elevated CO 2  (eCO 2 , 720 ppm) for 8 weeks. Elevated CO 2  increased plant growth, shoot: root ratio, net assimilation of CO 2 , leaf chlorophyll, and water use efficiency (WUE), but decreased plant water use. Salinity decreased growth, shoot: root ratio, net gas exchange and water use. Neither salinity nor eCO 2  affected leaf chlorophyll fluorescence (Fv/Fm), but CC had higher Fv/Fm, leaf gas exchange, chlorophyll, N and Ca than CM. Although salinity increased leaf Cl and Na in both genotypes, CC had higher leaf Cl, but lower Na than CM. Salinity-induced decreases in leaf osmotic potential increased leaf turgor, especially at eCO 2 . There were no interacting effects of eCO 2  and salinity on plant growth, but salinity decreased WUE more at eCO 2  than at aCO 2  in CM; but not in CC. Elevated CO 2  decreased leaf Cl and Na in CC, but tended to increase both ions in CM leaves. Patterns of Cl and Na responses in roots generally were in opposite direction to their respective responses in leaves. Thus, the modifications of citrus seedling responses to salinity by higher growth and lower water use at eCO 2  were not only species dependent, but also involved whole plant allocations of Na and Cl.
